Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time your schedule was badly off from what production actually built. What happened?
What they are checking: Whether they dig into why plans and reality split, and fix the inputs, instead of just replanning each week.
How do you run a weekly scheduling or S&OP meeting so it leads to decisions?
What they are checking: Whether they can lead a cross-functional meeting that ends with clear commitments, not just status updates.
What would you do
A customer wants to pull in an order, but it would push out another customer's order. What do you do?
What they are checking: Whether they surface the tradeoff to the right decision makers instead of quietly choosing a winner.
A key component is short and won't arrive for three weeks. How do you rework the schedule?
What they are checking: Whether they resequence intelligently to keep the line productive and tell customers early.
Production complains that the schedule changes too often. How do you respond?
What they are checking: Whether they take churn seriously and find ways to reduce it, since constant changes hurt efficiency and quality.
About the work
Walk me through how you build and maintain a master production schedule at an electronics manufacturing site.
What they are checking: Whether they understand balancing customer demand, material availability and capacity into a realistic plan.
How do you decide what goes inside the frozen zone of the schedule and how firmly you hold it?
What they are checking: Whether they know time fences and can protect stability on the floor while still responding to customers.
How do you use MRP output, and how do you know when it's giving you bad signals?
What they are checking: Whether they understand MRP depends on clean data, and can spot bad lead times or bills of materials.
How do you account for constraint resources, such as SMT lines or test equipment, when scheduling?
What they are checking: Whether they schedule to the bottleneck rather than loading every area as if capacity were unlimited.
Which metrics would tell you the schedule is working?
What they are checking: Whether they track schedule attainment, on-time delivery and stability, and understand what each one reveals.
